MACHINE FOR PEELING POTATOES.

SPEGIFIGATION forming part of Letters Patent No. 521,495, dated :rune 19, 1894.

Application filed .Tune 26 1 8 93.

To all whom it may concern:

Be it known that I, DAVID GRANT, a citizen of the United States, residing at Chicago, in

the county of Cook and/State of Illinois, have' invented a new and useful Improvement in Machines for Peeling Potatoes, of which the following is a specification.

The invention relates to machines wherein the potatoes are fed into a hopper, therequisite quantity at a time, and the machine set in motion, and by the abrading action produced by the mechanism of the machine peels the potatoes, and the same are dumped out of the machine, as will be more fully described herein.

The invention consists in the devices set forth in the claims hereof.

Reference will be had to the accompanying drawings, in which-- Figure 1 isa side vertical sectional view, through the center of the machine on line 2. 2. Fig. 2. Fig. 2. is a rear end view of the machine. Fig. 3 is a front view of the'machine with the receiving box in section on line 4. 4. Fig. 1. Fig. 4 is a vertical end sectional view 0n line 3. 3. Fig. 1. Fig. 5 is a side View of one of thebrush blades. Fig. 6 isafrontview of the grating surface on the inner side of the drum of the machine.

In the drawings A designates the frame of the machine, which is bolted to the floor at (1, and supports in bearings a the driving shaft B of the machine. Pivoted in these bearings a are two arms C C bolted to the side of the box or casing of the machine D,7 to the front of this casing there is fixed the receiving box D and the whole is held in a xed position by the locking arm D2 which has holes d engaging a pin on the side of the box D and is pivoted to the frame at cl2 Through the center of the case D and carried in bearings at the ends thereof; there runs a shaft D7 which carries a rotary steel bladed brush E On the interior of the case D there is a drum F which is carried on rollers f f f f xed to the interior of the case D. At the rear end of the case D are two shaftsG. G carried in bearings on the case D these shafts carrying sprockets.g2 g3 and are driven by chains g g from sprockets Serial No. 478,901. (No model.)

b 11' on shaft B which is driven by band BC The sprocket wheels g2 g3 are provided with ordinary grip clutches g4 g5 whereby they may be engaged or disengaged to their respective shafts. The brush E is driven by gear wheel G2 engaging gear wheels G3 G4, on shafts G G and the drum F is provided with gear teeth f at its end engaging gears C G6 77 H G5 77 N Gl, N GI),

is a gateway D3 which is Water tight and is locked in place by the bar CR In the receiving box D below the gate D3 there is a receiving basket D4 which is removable, and is made of Wire or other material whereby it acts as a strainer. In the same box D' below the receiving basket there is a removable screen D5 and below this screen D5 there is a space for waste water which may be drawn off by removing the plug dit The bottom of the case D is made to incline toward the box D and the drum F is made conical and the rotary brush E is made to conform to the drum F. The rotary brush E is made of four or more die visions of steel blades e which are shaped at their outer ends as shown at e. On the interior of the drum F there are three sets of gratings F and three straight bars F2. To the case D there is a hopper D6 whereat the machine is fed.

The operation of the machine is as follows Water is supplied filling the case up about midway, then a sufficient quantity of potatoes is supplied and the machine set in motion fromY the band wheel B only the `clutch g4 engaging its sprocket. The shaft G revolves and drives the brush E in one direction and the drum F in the other direction thus rolling the potatoes over and over in contact with the blades e and the gratings F and bars F2 and thus all sides of the potatoes are brought in contact In the front end of the case D there with the ends of the brushes e and thus the o'uter coating is abraded away, and the potatoes travel along down the incline to the gate D3 and when the action has been suficient the operator opens gate D3 and disengages the locking bar D2 and tilts the case forward and dumps the potatoes into the IOO basket D4. The water drains olf to the bottom of D and the peelings are caught on screen D5 and the potatoes are removed in basket Dt When the skins of the potatoes are hard and tough the brush is made to revolve, by shifting the clutches g4, g5, in the direction of the arrow Il Fig, 4, and when the skins are tender the brush is made to revolve in the direction of the arrow I.

l. In a machine for peeling potatoes, a frame A a case D pivoted to said frame, a receiving box D fixed to said case, a revolnble drum F and rotary brush E within said case, driving mechanism consisting of a horizontal shaft i driving shafts G G by suitable mechanism, clutches for engaging and disengagi ng said mechanism with shafts G G, gears G5 and GG engaging teeth on said drum and gears G3 and G4 engaging gear G2 on shaft D7 of brush substantially as shown and described.

2. In a machine for peeling potatoesarevoluble drum F `and a rotary brush E revolving Within said drum said brush having iiexible steel blades curved at their extremities as shown at e, in combination with mechanism for reversing the direction of travel of the brush in order to change the application of the curved ends of the blades on the stock to be peeled to suit the nature of said stock.

3. In a machine for peeling potatoesa revoluble drum F having a series of straight bars F2 and a series of V-shaped projections F on its interior in combination with a rotary brush E substantially as shown.

4. In a machine for peeling potatoes a frame i A` carrying a horizontal driving shaft B, a case D pivoted to frame A concentric with the shaft 13, a rotary drum F revoluble within said case, a rotary` brush E revoluble within said drum, mechanism for driving said drum and brush from the shaft B whereby the same may operate in any desired position of` theeasefD,withrelation to frame A,. mechanism for holding said case D1 in different positions withLrelationto said frame A wherebytheangle of incline of travel of stock through the drum` may be varied to suit thevarying condition` of stock.

In witness whereof I4 haveherenniofsuhscribed my name in the presenceof two witnesses.
